FABRIC BED-BOTTOM.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application led January 15, 1919. Serial No. 271,204.

To all whom t may concern:

Be it known that I, JOSEPH CIPOLLA, a subject of the King of Italy, butnow residing at the city of Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and usefulImprovements in Fabric Bed-Bottoms, of which the following is aspecification.

My invention relates to a wire fabric bed bottom interlaced in formingthe same and surrounding therefor having the end members connected tothe side members by interposed coiled tensioning springs and in betweenwith straining diagonally disposed springs for maintainlng the bedbottom throughout under a uniform tension for greater comfort and forthe avoidance of sagging in portions under undue pressure exerted in oneportion tendin to distort the surface of the bottom, which 1scompensated for or taken up by other portions through adjustment ofmembers of the framing in respect to each other, under the load orstrain.

The principal object of my invention, as thus defined, and infurtherance of such, as features thereof, consists of a fabric wire bedbottom constructively arranged in substantially the manner hereinafterdescribed and claimed.

The nature, scope and characteristic features of my invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof; in which- Figure 1,is a top or plan view of a fabric wire bed bottom, embodying theessential main features of the same.

Fig. 2 is a transverse sectional view on the line m, of Fig. 1; and

Fig. 3 is a fragmentary sectioned end elevation of one of the side andof the end members of the supporting framing and the connecting coiledsprings and straining tensioning coil springs of the present invention,as an embodiment thereof.

Referring to the drawings e, is the bed bottom comprising wire springsinterlaced together to form the surface of the fabricated bottom andwhich throughout is of the character as illustrated, in Figs. 1 and 2.

The supporting framing o, consists of preferably thin metal end membersb and b1, and similar side members b2 and b3.

These members, respectively, are coupled to each other by means ofinterposed coiled horizontally arranged springs c1 and c2, and inbetween the same a diagonally disposed coiled or other type of springo8, and which is designated as the tensional or straining spring of eachseries in connection with the said end and side members of the saidsupporting-framing c, adjacent to the respective four corners of thebed-bottom. The fabricated wire bed-bottom is fixed to the side and endmembers of the said supportingframing, in preferably, the manner asillustrated in Fig. 1, so as thereby to stabilize the whole through thearrangement of the interposed horizontal and diagonal springs c1, 02 andc3, in direct connection with the said end and side members of theframing, but not with the bed-bottom proper; and which arrangementconstitutes the means, whereby pressure either normal or abnormalexerted o'n the bed-bottom in any portion is compensated for by the saidside and end member springs at the respective points of connection fortaking up the same under either direct or indirect strain; and hencethere is provided a bed-bottom of a decidedly comfortable character aspractice has demonstrated, and a bottom aswell that can be maintained ina highly sanitary condition, at all times for use.

Having thus described the nature and objects of my invention, what Iclaim as new and desire to secure by Letters Patent is The combination,in a bed-bottom, of end strips, a fabric extending to the end-strips andinterlaced therewith, broad side strips shorter than the fabric andinterlaced therewith, the side strips connected at their ends to theends of the end-strips by helicals, some extending longitudinally andsome diagonally to form spring equalizing and straining means for thefabric, for maintaining uniform positioning tension of the same, againstsagging under normal and abnormal pressures.

In witness whereof, I have hereunto set my signature in the presence oftwo subscribing witnesses.
